A Geometry-based Stochastic Wireless Channel Model using Channel Images

1 code implementation11 Dec 2023 Seongjoon Kang

Due to the high complexity of geometry-deterministic wireless channel modeling and the difficulty in its implementation, geometry-based stochastic channel modeling (GSCM) approaches have been used to evaluate wireless systems.

Terrestrial-Satellite Spectrum Sharing in the Upper Mid-Band with Interference Nulling

no code implementations21 Nov 2023 Seongjoon Kang, Giovanni Geraci, Marco Mezzavilla, Sundeep Rangan

The growing demand for broader bandwidth in cellular networks has turned the upper mid-band (7-24 GHz) into a focal point for expansion.

Coexistence of UAVs and Terrestrial Users in Millimeter-Wave Urban Networks

no code implementations19 Sep 2022 Seongjoon Kang, Marco Mezzavilla, Angel Lozano, Giovanni Geraci, Sundeep Rangan, Vasilii Semkin, William Xia, Giuseppe Loianno

5G millimeter-wave (mmWave) cellular networks are in the early phase of commercial deployments and present a unique opportunity for robust, high-data-rate communication to unmanned aerial vehicles (UAVs).

Wireless Channel Prediction in Partially Observed Environments

no code implementations3 Jul 2022 Mingsheng Yin, Yaqi Hu, Tommy Azzino, Seongjoon Kang, Marco Mezzavilla, Sundeep Rangan

Site-specific radio frequency (RF) propagation prediction increasingly relies on models built from visual data such as cameras and LIDAR sensors.

Simultaneous Localization and Mapping

Understanding Energy Efficiency and Interference Tolerance in Millimeter Wave Receivers

no code implementations1 Jan 2022 Panagiotis Skrimponis, Seongjoon Kang, Abbas Khalili, Wonho Lee, Navid Hosseinzadeh, Marco Mezzavilla, Elza Erkip, Mark J. W. Rodwell, James F. Buckwalter, Sundeep Rangan

Power consumption is a key challenge in millimeter wave (mmWave) receiver front-ends, due to the need to support high dimensional antenna arrays at wide bandwidths.

Millimeter-Wave UAV Coverage in Urban Environments

1 code implementation5 Apr 2021 Seongjoon Kang, Marco Mezzavilla, Angel Lozano, Giovanni Geraci, William Xia, Sundeep Rangan, Vasilii Semkin, Giuseppe Loianno

Additional dedicated (rooftop-mounted and uptilted) base stations strengthen the coverage provided that their density is comparable to that of the standard deployment, and would be instrumental for sparse deployments of the latter.

Lightweight UAV-based Measurement System for Air-to-Ground Channels at 28 GHz

no code implementations31 Mar 2021 Vasilii Semkin, Seongjoon Kang, Jaakko Haarla, William Xia, Ismo Huhtinen, Giovanni Geraci, Angel Lozano, Giuseppe Loianno, Marco Mezzavilla, Sundeep Rangan

Wireless communication at millimeter wave frequencies has attracted considerable attention for the delivery of high-bit-rate connectivity to unmanned aerial vehicles (UAVs).
